Circuit Breakers

Circuit Breakers are devices used in place of a fuse to protect a circuit. There are manually resetable and automatic resettypes of circuit breakers. Manual reset breakers remain open on overload until the reset button is depressed. Auto-resetbreakers cycle or "continuously" reset until the overload is corrected. "Non-cycling" type II circuit breakers remain open untiloverload situation is corrected. Power must be disconnected for breaker to reset.

Pressure Switches are used to cycle the A/C compressor or clutch either on or off, or both, (depending upon the design of the switch) whenpressures in the A/C system either exceed or fall below the proper operating pressures. In some systems, pressure switches are also usedto engage the engine cooling fan. There are two basic groups of pressure switches, those normally open, and those normally closed in theirfactory settings. Normally open switches disallow current flow within their factory setting range. Normally closed switches allow current flowwithin their factory setting range. Switches should be replaced with the same type operation and pressure settings. Low pressure switchesactivate (open or close depending on whether the switch is normally open or closed) on pressure drop. High pressure switches activate onpressure rise. While the settings listed reflect factory settings, most switches will fluctuate + or - 3 to 10 p.s.i. A "quick find" chart is shownbelow for your convenience (does not include GM or Ford Accumulator, pressure cycling type).

RelaysRelays are basically remote control switches operated by an electro-magnetically produced force which opens or closes the relay’s contacts

through which the main power current flows. (See Illustration A) Relays are normally used to provide minimum resistance on leads between

a power source and consumer (motor, clutch coil, lamp, etc.). In order to keep resistance (which results in voltage drop) to a minimum, wire

leads need to be as short as possbile and have a sufficient cross-section diameter/gauge size. The inclusion of a relay means that the powercurrent can be routed directly from power source to consumer, and that the cable section can be correspondingly large. The weaker controlcurrent between the relay and control switch means that even small cable sections produce negligible voltage drop (See Illustration B).

There are 3 types of relays, normally open, normally closed and the change-over type, as shown below. Relays are available in 12 and 24v.

1. A normally open relay is used to close the electrical circuit between power source and consumer (the consumer is switched on).

These type of relays are operated by means of switches, impulse generators, or control devices.

2. In practice, the normally closed function is performed by the change-over relay. A normally closed relay is used to break the circuit

between power supply and consumer (the consumer is switched off). One application would be to use this type of relay in conjunction

with starting a vehicle to reduce load on the battery.

3. The change-over relay changes the current path from one electrical consumer to another. The relay is operated by a dash control

switch. A typical application would be used in a compressor clutch/condenser fan circuit. Change-over relays can be used as normally

open, normally closed, or change-over type relays.

Eliminating harmful voltage spikes can be accomplished by using relays supplied with resistors and diodes. Voltage spikes from

300v to 500v can momentarily occur when a relay is switched off. Sensitive electronic components can be damaged or malfunction if these

spikes reach the vehicle electrical network without suppression. A relay with a resistor (Illust. C) reduces these voltage spikes to less than

100v. A relay with a diode (Illust. D) eliminates them completely. The correct polarity of the connections to be made can be found on on the

relay itself.

Truck Air Parts supplies relays for both OEM applications and add-on/universal type installations. When installing a universal or add-on

relay to an electrical circuit, always check the relay’s configuration beforehand to insure the proper relay is used for the application.

Superheat Switches and Thermal Limiters

Superheat Switches (and thermal limiter fuses) are found on some earlier model Chev/GMCtrucks. These two components work in conjunction with one another. When the internalcompressor temperature rises due to a loss of refrigerant or a restriction in the system, thesuperheat switch closes and allows current to travel to the thermal limiter fuse, melting thefuse, thereby preventing current from operating the compressor and clutch.

QUICK REFERENCE CHARTTHERMOSTAT SWITCH SPECIFICATIONS

The thermostatic switch controls the electrical circuit to the compressor clutch. Most thermostat switches have a capillary tube which is

inserted into the fin area of the evaporator coil to sense its temperature. Matching both the original location and the depth of the tube

insertion during replacement is critical to obtaining correct system performance. Some thermostats are adjustable, others are fixed in

their settings. In addition, some are solid state controls (Thermisters) and are used in conjunction with a probe to sense evaporator

temperature. Excessive cycling of the clutch, or no cycle at all, may indicate a malfunctioning thermostatic switch.
